' Application filed January 27, 1891. Serial N0.'s79,223. (No model.)

1'0 all whom it may concern:

Be it known that we, PATRICK J. MURPHY and TIMOTHY F. MCCARTHY, citizens of the United States, residing at Alexandria, in the county of Alexandriaand State of Virginia, have invented certain new and useful Improvements in Car-Couplings; and we do hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to car-couplings; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section through the car-coupling. Fig. 2 is a front view of the coupling with the link re moved. Fig. 3 is a cross-section through the coupling, taken on the line a: 03 in Fig.1 and looking in the direction of the arrows. & is a plan view of the coupling from below.

Both portions of the coupling are alike, and each of them consists of a hollow rectangular stem A, adapted to be secured to the end of a car and provided with a chamber B at its front end.

B is an ordinary coupling-link adapted to unite the two parts of the coupling.

0 is a rearwardly and downwardly inclined tongue pivoted on the pin 0 in the upper part of the chamber B.

C are bosses on the tongue, and c are semicircular lugs in the said chamber, which lugs engage with the bosses O and relieve the pivot-pin of the strain of hauling the car, which would otherwise be thrown upon it.

D are inclined shoulders in the lower front part of the chamber B, and b is a space between the said shoulders wide enough to permit the end of the tongue to pass through it when the cars are to be uncoupled.

E is a hook provided with a rectangular shank e, which slides in the vertical hole 6' in the rear part of the chamber B. The link rests upon the tops of the shoulders D,being guided into the chamber by the inclined front sides of the said shoulders and the flaring shape of the front opening of the said chamher. The rear end of the link is engaged by Fig.

the hook E, and the weight of the hook and its stem, together with the pin 1), which passes through the stern and comes against the under side of the chamber, holds the said link,

in a horizontal position, ready to be thrust into engagement with the other part of the coupling on the end of the opposed car. hen the link enters the chamber B,'it raises the tongue O, which falls into the opening of the link and prevents its withdrawal from the chamber.

F is a transverse bar sliding close behind the shoulders D and passing through holesin the sides of the chamber. This bar is of the same height as the shoulders, and when pushed in, as shown in Fig. 1, it prevents the end ofthe tongue from being pulled forward by the link through the space 1) between the said shoulders. The end f of the bar F is lower than the main portion of the bar, so that when the said bar is drawn out, as shown in Fig. 2, the end of the tongue may pass out of the space I) over the end f of the bar.

G is a slot in the bottom of the chamber B, and g is a pin which slides backand forth in the said slot, and is screwed into the said bar F, so that the transverse movements of the said bar are limited by the pin coming against the ends of the slot.

The bar F is provided with an eye upon its end for moving it back and forth. Any approved actuating mechanism may be connected to this eye, so that the bar may be operated from the side or from the roof of the car, and so that there will be no need of going between the cars to uncouple them by pulling out the said bar.

\Vhat we claim is 1. In a car-coupling, the combination, with the stem and the chamber at its front end, of a coupling-link adapted to enter the said chamber, a rearwardly and downwardly inclined tongue pivoted in the upper part of the chamber, and asliding transverse bar for retaining and releasing the lower end of the. 9

tongue, substantially as and for the purpose set forth.

2. In a car-coupling, the combination, with the stem and the chamber at its front end, of the pivoted tongue provided with laterallyprojecting bosses at its upper end, the semicircular lugs in the chamber for the said bosses to engage with, and a sliding transverse bar adapted to retain the lower end of the tongue within the chamber, substantially as and for the purpose set forth.

3. In a car-coupling, the combination, with the stem and the chamber atits front end pro vided with the inclined shoulders having a space between them, of the tongue pivoted in the upper part of the chamber and the sliding transverse bar adapted to prevent the tongue from passing through the said space when the bar is pushed in and having a projecting pin engaging with a cross-slot in the bottom of the chamber for limitingthe movement of the said bar, substantially as and for the purpose set forth. r

4. In a car-coupling, the combination, with the stem and the chamber at its front end provided with the inclined shoulders, as set forth, of the link adapted to rest on the said shoulders and the hook provided with a vertical rectangular stem adapted to slide in a hole in the rear part of the chamber, and a cross-pin through the end of the stem, whereby the link may be held in a horizontal position, substantially as and for the purpose set forth.

5. In a car-coupling, the combination, with the stem and the chamber at its front end, of a coupling link adapted to enter the said chamber, a rearwardly and downwardly inclined tongue pivoted in the upper part of the chamber, a sliding transverse bar for retainin g and releasing the lower end of the tongue, a pin sliding in a slot in the bottom of the chamber and adapted to limit the movements of the said bar, and a hook provided with a vertical rectangular stem adapted to slide in a hole in the rear part of the chamber and to hold the said link in a horizontal position, substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
